BMW TwinPower Turbo eight-cylinder petrol engine in the BMW 550i.

Ability: with the eight-cylinder petrol engine in the BMW 550i you can exploit 300 kW (407 hp) or simply enjoy an impressive 600 Nm as of 1,750 rpm. So what is the secret of the effortless short bursts?

It is the turbochargers in the V between the cylinders. The special, compact design of the BMW TwinPower Turbo shortens exhaust paths to provide direct responsiveness – while the double-Vanos distributes the torque optimally across the entire speed range.The 5.0 seconds in which the BMW 550i accelerates from 0 to 100 km/h are as impressive as the engine's ability to turn any touch of the accelerator into immediate acceleration at any time.

When it comes to utilising energy efficiently, the BMW 5 Series Sedan holds the key: precision. With each combustion process, the High Precision Injection piezo injectors pump fuel into the combustion chambers at 200 bar with 400 Nm of pure power being delivered to the crankshaft. It's incredible how so little fuel can manifest itself into so much power.

Now you can accelerate at any time and never have to worry about high levels of fuel consumption.

The figures for fuel consumption and CO2 emissions depend on the wheel and tyre sizes selected.
